The APCUIterator class

(PECL apcu >= 5.0.0)

Introduction

The APCUIterator class makes it easier to iterate
over large APCu caches. This is helpful as it allows iterating over large
caches in steps, while grabbing a defined number of entries per lock instance,
so it frees the cache locks for other activities rather than hold up the
entire cache to grab 100 (the default) entries. Also, using regular expression
matching is more efficient as it's been moved to the C level.
